  • NSTableView not refreshing when calling method from different class

    - by Matt S.
    I have a table view that gets refreshed two different ways. One is through a button and the other is when I call my refresh method, which is the same method that I use for the button, but for some reason, when I hit the button it works, but when I call it through a different class it doesn't. Here's the code that I use to refresh the tableview: Msqv *qv = [Msqv new]; [qv refresh:self]; //refresh is an IBAction that is used by the button

  • Python file - Want to change it to a function or a class

    - by curious2know
    Hello, I have a python program/file that I want to run repeatedly and calculate the averages of some variables over these runs. To do so, I thought it might be convenient to convert this program into a function or a class. One way I can think of is to add a def Main(): line at the top and indent every line manually within it. Is there an easier way? I am using pydev on eclipse. Thanks.

  • [Symfony] Accessing user session from a custom routing class

    - by David
    Is there some way to acces the user object from a custom routing class? I'd like to add a parameter when generating a url, and that parameter is inside the user session, so I need to access it. The only way I found to access is using the sfContext::getInstance()-getUser(), but it's known to be inefficient. Thanks!

  • C# (non-abstract) class to represent paths

    - by user289770
    I'm looking for a C# class that represents a file system path. I would like to use it (instead of strings) as the data type of variables and method arguments (top reasons: type safety, concat-proof, logical comparisons). System.IO.Path provides most of the functionality I want, but it is abstract. System.IO.FileInfo, as I understand, performs IO operations to do its job. I only want a wrapper for the path string. Thanks!

  • Boost class/struct serialization to byte array

    - by Dave18
    does boost library provide functions to pack the class/struct data into a byte array to shorten the length of serialized data? Currently i'm using stringstream to get the serialized data, for example - struct data { std::string s1; std::string s2; int i; }; template <typename Archive> void serialize(Archive &ar, data &d, const unsigned int version) { ar & d.s1; ar & d.s2; ar & d.i; } int main() { data d; d.s1 = "This is my first string"; d.s2 = "This is my second string"; d.i = 10000; std::stringstream archive_stream; boost::archive::text_oarchive archive(archive_stream); archive.operator <<(d); } How would i use a byte array instead of stringstream for data?

  • Adding class constraints to typeclass instance

    - by BleuM937
    I'm trying to implement the Cantor Pairing Function, as an instance of a generic Pair typeclass, as so: module Pair (Pair, CantorPair) where -- Pair interface class Pair p where pi :: a -> a -> p a k :: p a -> a l :: p a -> a -- Wrapper for typing newtype CantorPair a = P { unP :: a } -- Assume two functions with signatures: cantorPair :: Integral a => a -> a -> CantorPair a cantorUnpair :: Integral a => CantorPair a -> (a, a) -- I need to somehow add an Integral a constraint to this instance, -- but I can't work out how to do it. instance Pair CantorPair where pi = cantorPair k = fst . cantorUnpair l = snd . cantorUnpair How can I add the appropriate Integral constraint to the instance? I have a vague feeling I might need to modify the Pair interface itself, but not sure how to go about this.

  • If Html File Has No Ending "/tr" Tag OR "/td" Tag Then HTML Agility Pack Does Not Read That Informat

    - by Harikrishna
    I am using HTML Agility Pack to parse html content. I am using parsing to extract table information. It works. But if there is no ending "/tr" tag or "/td" tag then it does not parse that information perfectly.(in which there is no ending tr tag or td tag.) Like <TABLE border=0><TBODY><TR height=20><TD class=xl27boL noWrap width="7%">01890345&nbsp;</TD> <TD class=xl27boL noWrap width="4%">1416</TD> <TD class=xl27boL noWrap width="7%">kjlkjkls&nbsp;</TD><TD class=xl27boL noWrap width="4%">14:01:57&nbsp;</TD> <TD class=xl27boL noWrap align=left width="15%">Football</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD> <TD class=xl27boL noWrap align=right width="5%">50&nbsp;</TD> <TD class=xl27boL noWrap align=right width="5%">4997.2500</TD><TD class=xl27boL noWrap align=right width="7%">249862.50&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boRLnoWrap align=right width="8%">249612.64&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">4997.2500</TD><TD class=xl27boL noWrap align=right width="7%">249862.50&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">249.86</TD><TD class=xl27boL noWrap align=right width="5%">4992.2528</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD> <TD class=xl27boRL noWrap align=right width="8%">249612.64&nbsp;</TD> </table> So for that what should I do ?
